I've got them hooked up and trying to run my receiver calibration to balance everything. One of them as nothing coming out the driver. STarting my troubleshooting, hope it is something simple like a cable that came loose...

I've been spending a lot of time trying to get everything calibrated. My initial plan was to use the Velodyne SMS-1 to adjust the 350's and let the 600 just go through the receiver. The freq response was very smooth with no EQ. The problem was when I tried to adjust down some of the peaks using the sms-1(which generally is very easy to do) they actually got higher. I think it has something to do with interactions from having multiple subs and all the waves bouncig/colliding with each other.

I'm tossing around the idea of using the SMS-1 to find the best placement for my subs and then sell it.

My main problem is trying to calibrate SPL with the meter. I calibrated them all to 75dB's individually, but when they are all on, the dB's jump by about 9 dB's. Maybe I'm supposed to calibrate them lower so the sum gets me back to match the other speakers.

The 600 is crazy, I have to have the volume on the 600 at the lowest MIN setting and my Denon at -5dB and it is still higher than 75dB's on the meter, that is crazy. Because of this I have to really turn up the gain on the 350's, since the Denon is at -5dB. arggggggg

Not sure that is it, I talked to Ian and Jakeman. Both said the 350v3s would match well to the 600. I think part of the problem is my Denon 2805. I know Alan and other say to put it at 0 for the sub level and then adjust up/down form the sub. There is no way I can do that with the 600. I would be hitting 90dB's with the receiver pink noise.

I think mojo has to run his Denon at -9. The subs sound awesome togethor, I'm just trying to figure out the best way to calibrate them all.
